Changing the remote controller
mode
When you use any Integra/Onkyo products other
than the NAC-2.3 in the same room, the
operations made with the NAC-2.3s remote
controller may also cause the other Integra/Onkyo
products to operate. To avoid this, you can change
the remote controller mode both for the NAC-2.3
and its remote controller choosing from three
modes (1, 2 or 3).
To change the remote controller mode for the
remote controller, hold the Standby button on the
remote controller and press the Select button, then
release these buttons simultaneously. Within 5
seconds after releasing the buttons, enter the
appropriate mode (1, 2 or 3) using the numeric
keys. The default mode is 1 for both the remote
controller and NAC-2.3.
After changing the remote controller mode, make
sure that the remote control Remote ID code on
the NAC-2.3 is set to the same mode as the remote
controller. (see Page 57)
